#emc | Logs for 2007-01-30

[01:09:10] <fenn> ah that one's good for many occasions - "god didn't do it, we did"
[01:09:38] <cradek> I hope that wasn't mean, I didn't mean it to be
[01:10:50] <fenn> i thought it was funny, but, i'm an evil bastard i guess
[01:13:53] <cradek> well it sure seemed true from where I sit
[01:19:47] <CIA-8> 03fjungclaus 07TRUNK * 10emc2/share/axis/tcl/axis.tcl:
[01:19:47] <CIA-8> - Added menu entries for copy/paste from/to mdi history
[01:19:47] <CIA-8> - Moved mdi entry field key bindings to axis.py
[01:21:28] <CIA-8> 03fjungclaus 07TRUNK * 10emc2/src/emc/usr_intf/axis/scripts/axis.py: (log message trimmed)
[01:21:26] <CIA-8> Adapted mdi history behaviour to results of our discussion on irc:
[01:21:26] <CIA-8> - Up to 1000 history elements
[01:21:26] <CIA-8> - Choosing an history element by mouse or up/down+enter will
[01:21:26] <CIA-8> copy the element to end of history list (instead of moving it
[01:21:27] <CIA-8> to the end of the list)
[01:21:31] <CIA-8> - CTRL-H for copying selected mdi history elements to clipboard
[02:30:59] <fjungclaus__> fjungclaus__ is now known as fjungclaus
[02:31:50] <fjungclaus__> fjungclaus__ is now known as fjungclaus
[02:32:41] <fjungclaus_> fjungclaus_ is now known as fjungclaus
[02:59:22] <tomp> Twingy: I discovered that you should add line/arcs to a sketch, not to the basic project. That wasn't obvious. and...
[02:59:56] <tomp> Twingy: I added a 180 degree arc and then another... http://imagebin.org/7085 the new arc began in middle of previous
[03:00:45] <tomp> this maybe 'expected' but kinda surprised me
[03:05:56] <Twingy> sec
[03:06:49] <Twingy> I'll take a look shortly, working on metric units and getting ready for another release
[03:07:05] <Twingy> fixed a few minor bugs
[03:07:55] <tomp> i'll try in metric, but think the problem is in the 180 degree, extruding gave me weird result.... making screen grabs now
[03:08:52] <tomp> yes, the app went away & said BAD BAD BAD BAD... on the terminal screen
[03:09:26] <Twingy> don't use metric
[03:09:35] <tomp> k
[03:10:17] <tomp> (BAD BAD... was from the 180, i didnt try metric )
[03:11:40] <Twingy> yes, just ignore that
[03:11:43] <Twingy> it's not really bad
[03:11:50] <Twingy> it was just a printf from testing
[03:11:54] <tomp> :)
[03:14:29] <ejholmgren> at least gcam doesn't goatse.cx you when it hangs :)
[03:19:21] <tomp> Twingy: maybe this is of use http://imagebin.org/7086
[03:20:33] <Twingy> hmm
[03:20:39] <Twingy> can you post that .gcam file
[03:20:53] <tomp> yep, just thinking bout dat...
[03:21:11] <Twingy> I'll take a look in about 10 minutes
[03:22:37] <tomp> it's binary. how to post?
[03:27:26] <Twingy> I usually place my files on my webserver
[03:27:33] <Twingy> do you have a webserver?
[03:27:38] <tomp> no
[03:27:45] <Twingy> otherwise you could attach in bugzilla
[03:27:47] <Twingy> file a bug
[03:27:51] <Twingy> and use attach file
[03:27:56] <tomp> k
[03:28:04] <Twingy> hrm
[03:28:04] <Twingy> I knew I forgot something
[03:28:10] <Twingy> let me add that versoin to bugzilla
[03:28:40] <Twingy> ok, go ahead
[03:29:49] <tomp> but i see more info... a 2 element shape of a single 180 deg arc, closed by a line ( a diameter), does similar, the whole shape disappears... going to bugzilla now (new territory for me, dont wait for it :)
[03:31:19] <Twingy> k
[03:31:34] <Twingy> I don't think I will have a new release until wednesday
[03:31:54] <tomp> no problem
[03:32:40] <Twingy> getting decent conversion between metric and imperial is a bit time consuming
[03:32:46] <Twingy> gotta update the bounds on all the widgets
[03:33:03] <Twingy> otherwise you'd be stuck with little 100mm x 100mm work spaces
[03:33:10] <Twingy> 100 inches x 100 inches is plenty
[03:33:49] <Twingy> plus the gridding has to change
[03:33:58] <Twingy> inch->0.1"->0.01"
[03:34:00] <Twingy> for metric
[03:34:09] <Twingy> it needs to be cm->mm->0.1 mm
[03:34:20] <Twingy> so it doesn't start at the base unit
[03:42:51] <A-L-P-H-A> anyone know what E.S.T. stands for, in regards to movies at theatres?
[03:43:28] <jepler> something seating time?
[03:43:50] <jepler> earliest?
[03:43:59] <A-L-P-H-A> english sub-titles?
[03:44:01] <A-L-P-H-A> <shrug>
[03:44:05] <A-L-P-H-A> I dunno what it means.
[03:44:14] <A-L-P-H-A> I should call the theatre tomorrow and ask.
[03:45:46] <ejholmgren> eastern standard time?
[03:45:53] <A-L-P-H-A> nope.
[03:46:02] <A-L-P-H-A> I know it doesn't meant that.
[03:51:19] <ejholmgren> apparently in spanish it means STD
[03:59:57] <tomp> Twingy: there is no 'attach file' on the gcam bugzilla page (http://gcam.js.cx/bugzilla/enter_bug.cgi), and, while the bugzilla faq says Just click on "Create an attachment". that doesnt exist either
[04:01:01] <Twingy> erm
[04:01:05] <Twingy> * Twingy takes a look
[04:01:07] <tomp> Twingy maybe you can just make a 2 element contour with a half circle closed by a line. that will exhibit the symptom
[04:01:31] <tomp> D
[04:02:09] <Twingy> you have to create the bug report first
[04:02:15] <Twingy> then if you view it there is a Create an Attachment link
[04:02:33] <Twingy> k
[04:02:34] <tomp> ah. that's intuitive :)
[04:02:39] <tomp> k
[04:02:38] <Twingy> I'll take a look
[04:03:43] <Twingy> ok tomp, I see it
[04:03:55] <tomp> k
[04:03:56] <Twingy> I'm pretty sure I know what that is
[04:04:45] <Twingy> metric is half done now
[04:05:03] <Twingy> think I will finish up tomorrow
[04:05:46] <tomp> bug report created, file attached & sent now, g'nite & thanks
[04:07:45] <Twingy> k, thx
[04:10:30] <A-L-P-H-A> EST = does mean english sub title.
[08:05:48] <tray> Hello, i've added a PCI parallel port card to my PC. I'm looking for ways to check if it's running ok. (noobie)
[08:18:28] <alex_joni> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?NetMos
[08:18:42] <alex_joni> those are the most common I know about
[08:22:22] <Dallur> morning
[08:22:30] <alex_joni> hi
[08:22:38] <A-L-P-H-A> hi
[08:23:01] <Dallur> hmm back on that embedded geode computer project now, and for the next year it seems
[08:24:10] <alex_joni> nice ..
[08:24:26] <alex_joni> I need to find something to do with mine..
[08:24:54] <Dallur> don't need to control anything ?
[08:24:59] <alex_joni> not atm
[08:25:36] <alex_joni> :(
[08:25:38] <Dallur> hmm you could always create a "house control" computer
[08:26:34] <Dallur> get a couple of those ethernet over power cables thingies and control all your stuff from your embedded computer :D
[08:27:04] <alex_joni> I'll reconsider that when I'll settle in :D
[08:30:48] <tray> thanks alex
[08:32:02] <fenn> embedded computers are only really needed for mobile stuff imho
[08:32:53] <fenn> if you're designing an industrial system you probably want something designed for the task
[08:32:56] <A-L-P-H-A> Dallur, atmel with an ethernet connection, and you're more than set... PIC/atmel + wifi, you're wireless. :)
[08:33:14] <fenn> atmel won't run an 802.11 protocol, no way
[08:33:31] <A-L-P-H-A> fenn, they have other chips that do, I believe...
[08:33:42] <fenn> have to struggle just to keep up with regular ethernet
[08:34:17] <A-L-P-H-A> at76c506a
[08:34:27] <fenn> (i dont consider a microcontroller a "computer" even if technically it is)
[08:35:03] <A-L-P-H-A> http://atmel.com/dyn/resources/prod_documents/AT76C515A_DS_5677AS.pdf
[08:35:36] <fenn> uh huh
[08:35:58] <fenn> so you're going to interface your microcontroller to an 80mhz arm controlling the wireless :D
[08:36:25] <A-L-P-H-A> who knows. :)
[08:36:45] <A-L-P-H-A> just as long as you don't go that "X" modular crap
[08:36:54] <fenn> only comes in bga
[08:37:34] <fenn> ffs you need an NDA just to get the datasheet?
[08:38:05] <alex_joni> fenn: there are plenty that run wifi
[08:38:17] <alex_joni> but atmel makes arm's too :)
[08:38:25] <fenn> yep
[08:38:30] <alex_joni> no reason for an arm7 not to work with wifi
[08:38:42] <fenn> what i meant was it makes more sense to just use the arm chip in the first place
[08:39:14] <alex_joni> right..
[08:39:38] <alex_joni> http://www.ethernut.de/en/hardware/enut3/index.html
[08:40:09] <fenn> ethernut is kinda crazy for most things
[08:40:21] <alex_joni> http://www.ethernut.de/en/wlan/index.html
[08:40:34] <alex_joni> fenn: why do you say that?
[08:41:03] <fenn> well, you might as well just get a ts-7400
[08:41:10] <fenn> and run debian on it
[08:41:53] <fenn> you dont need all the extra stuff just to get on an ethernet and send/receive data
[08:44:27] <alex_joni> I'd probably get one of these: http://www.olimex.com/dev/sam7-ex256.html
[08:45:06] <fenn> color lcd is an interesting touch
[08:47:11] <fenn> why is olimex's website so lame?
[08:47:23] <alex_joni> fenn: guess they stick out with grood producs/services :D
[08:48:28] <alex_joni> fenn: that's prolly a lame excuse :)
[08:48:45] <fenn> hmm $115.95
[08:48:57] <alex_joni> hang on.. I have a nicer one :)
[08:49:06] <alex_joni> just to find the damn link
[08:50:03] <fenn> i guess i just like ts-7200
[08:51:03] <alex_joni> wonder how emc would run on that ..
[08:51:14] <alex_joni> rtai has some version working for arm
[08:51:42] <alex_joni> oh, but that's for ARM7 :(
[08:52:29] <alex_joni> the fox is also nice
[08:52:30] <alex_joni> http://www.acmesystems.it/?id=4
[08:52:51] <fenn> i remember that
[08:52:56] <fenn> it comes in a plastic penguin
[08:53:08] <fenn> http://www.acmesystems.it/?id=21
[08:53:11] <alex_joni> http://www.acmesystems.it/?id=21
[08:53:12] <alex_joni> yeah
[08:53:54] <fenn> that would be nice for a wearable computer
[08:53:59] <fenn> with head mount display
[08:55:13] <fenn> usb stick + usb wifi
[09:17:38] <alex_joni> http://www.samsung.com/Products/Semiconductor/MobileSoC/ApplicationProcessor/ARM9Series/S3C2410/Picture2410k_1for2410tk.jpg
[09:17:46] <alex_joni> that's the one I was looking for :D
[09:19:29] <fenn> bleh
[09:19:40] <alex_joni> fenn: that's only the training kit
[09:19:45] <alex_joni> you can get it in smaller sizes
[09:19:58] <alex_joni> but that one (actually a cn copy) is about 150$ here
[09:20:13] <alex_joni> http://www.embed.com.cn/cpzs/picture/1677200652293026.jpg
[09:21:46] <alex_joni> http://www.nks.com.cn/uploadfile/2003111204557635.jpg
[09:23:05] <fenn> there's a lot of stuff on that board :)
[09:23:10] <alex_joni> yeap :)
[09:24:58] <fenn> * fenn reads about the "kliper" spacecraft
[09:28:11] <Martin_Lundstrom> hello, what is the application?
[09:28:47] <fenn> i have two apps in mind specifically, one a humanoid robot, the other as a wearable computer
[09:29:01] <Martin_Lundstrom> ok
[09:29:41] <paragon36> Morning All
[09:29:45] <Martin_Lundstrom> hi
[09:31:08] <alex_joni> can't you wear a humanoid robot?
[09:31:15] <alex_joni> err.. carry :D
[09:31:29] <fenn> if you're wearing it, then it's not a robot now is it?
[09:32:09] <Martin_Lundstrom> I saw a deme of the sony dog the other day, quite funny
[09:32:32] <Martin_Lundstrom> demo
[09:36:01] <paragon36> Morning Chaps! I am trying to source a 0 - 180V DC motor controller for a Denford Starmill but I do not know the HP is there a way of determining this?
[09:37:12] <lerman_> lerman_ is now known as lerman
[09:38:28] <Martin_Lundstrom> have no clue, is there a desent motor plate?
[09:39:26] <alex_joni> paragon36: do you have a current rating?
[09:39:31] <paragon36> It does'nt disclose the HP and I cant see the Amps as the label is partialy hidden
[09:39:55] <Martin_Lundstrom> bring your mirrors :)
[09:40:06] <fenn> just get something ridiculously oversized :)
[09:40:11] <fenn> 10kW oughta do it
[09:40:14] <paragon36> I think about 1 amp but not sure due to it being hidden .... yep
[09:40:16] <paragon36> lol
[09:40:28] <ds3> are you refitting the denford?
[09:41:03] <ds3> if I am reading the denford docs correctly, it has a VFD on there already
[09:41:53] <ds3> (been researching a denford lathe)
[09:42:58] <paragon36> ds3 In my haste I shorted the leads for the varible control to the Denford DC speed controller I am currently trying to debug the system but am at a loss. The unit uses 2* SCR and 2* op-amps. The op-amps have 12V supply but I am only reading 3v max at the inputs where a pot would be connectected to control the speed
[09:43:36] <paragon36> VFD = Voltage Freq Drive?
[09:43:52] <ds3> Variable Freq Drive; they seem to have a 3PH AC motor on there
[09:44:11] <ds3> have you looked to see if the schematics are posted on their website?
[09:44:57] <paragon36> This motor drive used to output 0 - 180V DC to the motor not AC. It takes 240V AC in
[09:45:16] <ds3> hmmm different system then the lathe
[09:45:23] <paragon36> I think the motor is a Baldor (or something like that)
[09:47:39] <paragon36> I am not familiar with this type of drive but from what I can see it uses 2 op-amps which in turn switch 2 SCR's which in turn send the chopped AC power through rectifier diodes to produce 0-180 VDC does this sound about right?
[09:48:08] <paragon36> Or plausable?
[09:48:36] <ds3> probally a the op-amps are setup as comparator to trigger on varying voltages?
[09:49:38] <paragon36> I am currently attempting to desolder the op-amps as I have bought some for replacement. Would you agree that these are probably the weekest part of the circuit?
[09:49:51] <ds3> I'd guess the SCRs
[09:50:00] <fenn> op amps are for current limiting
[09:50:50] <ds3> fenn: as in reading a sense resistor?
[09:50:53] <fenn> right
[09:51:45] <ds3> hmmm can't find the zip file URL on their site for the mill that I dl'ed by mistake last time
[09:51:51] <paragon36> Current Limmiting! What would be used to pulse the SCR's I cant see any other components on the board other than resisters (lots) some diodes and caps?
[09:52:20] <fenn> maybe they act as comparators too
[09:52:38] <ds3> fenn: how'd that work with an SCR since the only way it can turn off is if the AC line dips below 0?
[09:54:08] <paragon36> To determine the voltage the SCR's would be triggered late for lower voltage and early within the AC cycle for higher voltage output. Is this correct?
[09:54:09] <fenn> dunno, this is not the best way to reverse engineer a board
[09:54:29] <fenn> yes
[09:54:33] <paragon36> lol
[09:54:35] <ds3> paragon36: I'd suggest you post to their board
[09:54:53] <ds3> they actually are willing to answer q's for machines of that vintage
[09:55:01] <paragon36> Do they have a Forum now?
[09:55:07] <ds3> http://www.denfordata.com/bb/
[09:55:31] <paragon36> Excellent Thanks Chaps I'll give it ago.
[09:55:34] <ds3> if they still have copies of the docs/diagrams, most likely they will scan and post it
[09:55:52] <paragon36> Fingers Crossed!
[09:58:40] <paragon36> Would this work ok? http://cgi.ebay.co.uk/KB-BALDOR-BC142-3HP-DC-MOTOR-DRIVE-W-HEATSINK_W0QQitemZ290016457393QQihZ019QQcategoryZ1267QQrdZ1QQcmdZViewItem
[10:01:47] <ds3> doesn't say much about the control signal or isolation
[10:10:49] <paragon36> Sorry got called away! True it does'nt. BTW I have seen some drives but looking at the spec sheets they talk about comutator (2 wires) and motor drive (2 wires) are these for brushless DC motors?
[10:13:14] <fenn> could be for variable field motors
[10:14:26] <paragon36> So no good for my purpose then.
[10:16:04] <ds3> universal motors I think
[10:53:49] <ds3> bb... client screwed up
[11:15:54] <anonimas1> anonimas1 is now known as anonimasu
[11:16:24] <A-L-P-H-A> hey anonimasu.
[11:16:25] <anonimasu> hello
[11:16:35] <A-L-P-H-A> anonimasu? got pics of the schuablin now?
[11:16:44] <anonimasu> no
[11:16:47] <anonimasu> A-L-P-H-A: why?
[11:16:53] <A-L-P-H-A> want to see.
[11:16:55] <anonimasu> :)
[11:17:00] <A-L-P-H-A> cnc porn!
[11:17:00] <anonimasu> havent made any progress
[11:30:19] <A-L-P-H-A_> that was so much fun.
[11:30:22] <A-L-P-H-A_> computer just randomly went DEAD.
[11:30:26] <A-L-P-H-A_> like no power...
[11:30:27] <A-L-P-H-A_> at all...
[11:30:36] <A-L-P-H-A_> UPS went wonky I think
[11:31:24] <A-L-P-H-A_> A-L-P-H-A_ is now known as A-L-P-H-A
[11:43:15] <alex_joni> A-L-P-H-A: bet it was the CNC pr0n filter
[11:43:40] <A-L-P-H-A> :(
[11:43:43] <A-L-P-H-A> stupid net nanny.

[14:04:01] <jepler> loadrt not
[14:04:01] <jepler> Realtime module 'not' loaded
[14:04:14] <jepler> damnit, I asked you to load a realtime module
[14:04:19] <jepler> and you tell me it's not loaded ...
[14:05:09] <tomp> self-obfuscating programming
[14:37:44] <jepler> good morning awallin, Dallur
[14:37:47] <jepler> welcome, plattschnauze
[14:38:45] <awallin> hi jepler
[16:27:08] <giacus> hello boys
[16:30:27] <rayh> Hi gaicus.
[16:31:13] <giacus> hello rayh :))
[16:31:33] <rayh> What you doing these days?
[16:32:14] <giacus> rayh: these are very strange days
[16:32:18] <giacus> nothing ..
[16:32:19] <giacus> :D
[16:32:51] <giacus> listen music and fighing
[16:32:57] <giacus> a bit of relax :P
[16:34:13] <giacus> too much things to do, too few times :(
[16:34:35] <giacus> so.. taking a pause :D
[16:34:49] <rayh> I know something about "too few times"
[16:34:54] <giacus> hah
[16:35:13] <giacus> ;)
[16:39:46] <giacus> I just received a mail from a guy in palermo (IT), he was asking about CNC, i sent him here few days ago
[16:40:09] <giacus> and lot of time I can't see jymmm here around
[16:42:09] <skunkworks> Hey jackey - long time no see.
[16:58:54] <giacus> hi skunkworks !
[16:59:02] <giacus> sorry
[16:59:16] <giacus> :-)
[16:59:26] <SWPadnos> giacus, jymmm hasa new job, and works nights
[16:59:38] <giacus> ouch ..
[16:59:42] <SWPadnos> oh - hi :)
[16:59:49] <giacus> what job ?
[16:59:52] <giacus> O_O
[17:00:11] <SWPadnos> some computer / IT maintenance thing
[17:00:16] <giacus> ok, nice to know he's good
[17:00:55] <SWPadnos> well, I didn't say that :)
[17:01:02] <giacus> hahah
[17:01:14] <giacus> right, I sayd that
[17:01:20] <giacus> :D
[17:06:28] <jepler> oh boy, I made another blog with etch cnc. http://www.makezine.com/blog/archive/2007/01/etchasketch_cnc.html
[17:07:33] <SWPadnos> heh - you're world famous
[17:08:32] <jepler> and so yesterday accounted for 19% of all hits on the axis website
[17:08:35] <jepler> er, all hits this month
[17:08:54] <SWPadnos> impressive, considering that the month is just about over
[17:09:31] <alex_joni> SWPadnos: hi
[17:09:36] <alex_joni> wanted to ask you something
[17:09:42] <SWPadnos> hi Alex
[17:09:46] <SWPadnos> ask away
[17:09:59] <jepler> it just means there normally aren't many visitors
[17:10:00] <alex_joni> do you know of a good survailance solution on linux?
[17:10:10] <SWPadnos> like security camears?
[17:10:14] <SWPadnos> cameras
[17:38:25] <anonimasu> hello
[17:45:54] <alex_joni> SWPadnos: yeah
[17:57:09] <skunkworks> jepler: where you personally contacted by the ohio arts legal department?
[17:57:19] <anonimasu> *yawn*
[17:57:28] <anonimasu> alex_joni: yeah I found one before
[17:57:39] <anonimasu> www.freshmeat.net has it..
[17:57:52] <anonimasu> but I didnt get it to work as it depended on ancient deb packages
[17:57:59] <jepler> skunkworks: no, not yet
[17:58:31] <jepler> skunkworks: though I heard of someone who had trouble, and put this text on my website from the start: The Etch A Sketch® product name and the configuration of the Etch A Sketch® product are registered trademarks owned by the The Ohio Art Company. None of these trademark holders are affiliated with the AXIS website.
[18:01:20] <skunkworks> jepler: I was looking at the bottom of this site ;)
[18:01:22] <skunkworks> http://neil.fraser.name/hardware/etch/
[18:37:02] <awallin> jepler: can I ask what software you use for the 'jepler's feeds' page ? i.e. rss/atom etc aggregation into a webpage
[18:45:56] <awallin> hmm, there seems to be a lot of feed aggregators available for wordpress, maybe that's the way to go
[18:51:11] <alex_joni> * alex_joni runs home..
[19:03:05] <giacus> hi alex_joni jepler
[19:03:27] <giacus> ready for dinner :)
[19:04:00] <giacus> giacus is now known as giac_awy
[19:11:58] <jepler> awallin: the software is called "planet"
[19:12:54] <awallin> jepler: thx, I'm also looking at something that integrates with wordpress...
[19:13:22] <jepler> awallin: I don't think "planet" integrates with anything
[19:28:32] <Nicolas35LA> hi, is there a EMC2 version of the MS-Windows tkemc/emcsh.exe ?
[19:29:13] <cradek> no, but an old version will probably still talk to emc2
[19:29:25] <Nicolas35LA> I tried and it doesn't seem to work
[19:29:43] <Nicolas35LA> tcpdump shows the Linux EMC server getting the packets
[19:30:01] <cradek> there are good solutions for running X programs on windows displays now, in particular vnc
[19:30:13] <Nicolas35LA> I turned on debug on EMC on the linux server and it does talk for a while but then the client declares no connection
[19:30:29] <cradek> maybe that's a different/better approach?
[19:30:46] <Nicolas35LA> Yes but for this specific case it isn't a solution
[19:31:30] <Nicolas35LA> my goal is to run emc2 on an embeded linux board with limited resources
[19:31:34] <SWPadnos> Nicolas35LA, have you looked at Eric Johnson's "emctelnet"?
[19:31:41] <Nicolas35LA> I want to only run what is necessary on the embedde dboard
[19:31:47] <SWPadnos> or was it emcrsh?
[19:32:01] <jepler> I think he decided to call it emcrsh
[19:32:02] <Nicolas35LA> yes I looked at ti
[19:32:03] <Nicolas35LA> it
[19:32:35] <jepler> Nicolas35LA: all you need is time, expertise, and the source code to build a new emcsh.exe. We provide the source code
[19:32:37] <Nicolas35LA> basicaly what I want to do is have the GUI run on Windows/Mac and talk to the linux server with NML
[19:32:50] <Nicolas35LA> I am looking for examples to play with and get familiar
[19:32:57] <Nicolas35LA> I satrted with tkemc
[19:33:20] <Nicolas35LA> I have time and expertise
[19:33:22] <cradek> have you done this before with an earlier emc?
[19:33:31] <Nicolas35LA> Yes
[19:33:58] <Nicolas35LA> time is not a problem but before I jump I wanted to know what is done already to not reinvent the wheel
[19:34:00] <cradek> how did you solve the problems with the different systems finding the same ngc file?
[19:34:19] <SWPadnos> there's a Java client, though I'm not sure of the status (I think it's pre-pre-pre-Alpha :) )
[19:34:22] <Nicolas35LA> I first copy a tmp file to the server
[19:34:40] <Nicolas35LA> editing is done on the client
[19:34:47] <Nicolas35LA> the tmp file gets copied at run time
[19:34:49] <cradek> I see
[19:35:36] <SWPadnos> hmm - the client you use(d) with emc should be able to talk to emc2, with some .nml file changes
[19:35:39] <SWPadnos> (I think ??)
[19:35:50] <Nicolas35LA> yes
[19:35:58] <Nicolas35LA> no doubt
[19:36:00] <cradek> I think so too - sounds like you'll have to debug some more
[19:36:09] <Nicolas35LA> This works in EMC1
[19:36:28] <Nicolas35LA> but probably interfaces have changed in EMC2
[19:36:36] <jepler> we've changed the layout of many of the classes
[19:36:40] <jepler> the stat class most of all
[19:36:45] <Nicolas35LA> that explains it
[19:37:36] <jepler> maybe you should begin by using linux on both machines, just to make sure the network transport hasn't bitrotted completely
[19:38:21] <Nicolas35LA> I can do that. But it works fine from MS-Windows to Linux on EMC1
[19:38:31] <Nicolas35LA> It must simply be differences in interfaces
[19:38:40] <Nicolas35LA> I need to start from scratch it seems
[19:38:53] <SWPadnos> you may be able to start from a recompile of the windows client ...
[19:39:15] <SWPadnos> ie, port over the changed status and other things, and see where that gets you
[19:39:43] <Nicolas35LA> yes
[19:39:59] <Nicolas35LA> I was also considering using the emc.so that comes with Axis
[19:40:12] <Nicolas35LA> not sure how difficult it would be to port that to Windows
[19:40:30] <SWPadnos> windows + .so = boom!
[19:40:41] <Nicolas35LA> I said Port ;)
[19:40:44] <SWPadnos> heh
[19:40:45] <Nicolas35LA> not run
[19:40:54] <erDiZz> cygwin might help
[19:41:05] <SWPadnos> not in this case - it's beed covered
[19:41:09] <jepler> I don't know why it would be much harder or easier than the tcl library
[19:41:09] <SWPadnos> been
[19:41:34] <jepler> but if you want to run axis, you'll also have to make sure togl (the tk opengl widget) works on windows
[19:41:50] <Nicolas35LA> seems like a nice solution I can then use python on Windows to create a GUI
[19:42:09] <Nicolas35LA> or maybe run Axis :)))))
[19:42:31] <cradek> Nicolas35LA: are you tied to windows for some reason? if you don't need windows, you could even run perfectly well using just a live CD, no installation necessary
[19:42:47] <SWPadnos> I think your concern about "reinventing the wheel" can be laid to rest :)
[19:42:51] <Nicolas35LA> Yes, I am no fan of windows
[19:42:57] <Nicolas35LA> but I need to
[19:43:43] <cradek> I understand, but sorry I am not able to suggest anything but "start compiling stuff"
[19:43:50] <SWPadnos> as far as I know, emcrsh is the only truly remote UI for emc2
[19:44:14] <SWPadnos> everything else just runs with a network connection beween the UI code (still running on the EMC box) and the display
[19:44:47] <cradek> I don't understand the distinction
[19:45:05] <SWPadnos> vnc / remote X are basically the same thing as a KVM switch with a long cable
[19:45:18] <SWPadnos> the software still runs on the emc box, but is shown elsewhere
[19:45:36] <cradek> with his approach no gui code runs on the emc machine
[19:45:41] <erDiZz> ehm. one can run an X server on a Windows box
[19:46:03] <erDiZz> dunn'o how it'll do with OpenGL
[19:46:38] <SWPadnos> cradek, right - that's different from vnc/remote X, since those still run the user interface on the EMC box, but use a separate machine to actually draw the pixels
[19:46:58] <SWPadnos> erDiZz, I've used Axis on cygwin (with an old Parhelia card), and it works well
[19:47:36] <erDiZz> SWPadnos, you mean that X server which comes with cygwin?
[19:47:40] <Nicolas35LA> Did you use Axis to control a remote machine
[19:48:04] <SWPadnos> erDiZz, yes, cygwin/X
[19:48:21] <SWPadnos> Nicolas35LA, yes, but without an actual machine attached
[19:48:29] <Nicolas35LA> ok, so axis was running on linux but displaying to a remote Xserver on windows
[19:48:34] <jepler> I frequently run AXIS using the X protocol for remote display
[19:48:35] <SWPadnos> correct
[19:48:55] <SWPadnos> Nicolas35LA, that's the distinction I was trying to describe
[19:49:04] <Nicolas35LA> I know
[19:49:27] <jepler> I don't think (m)any people are using NML over the network
[19:49:28] <Nicolas35LA> our linux embedded board is small. I don't know about the extra load it would put on it
[19:49:33] <Nicolas35LA> I might try it
[19:49:43] <SWPadnos> what processor does it have?
[19:49:48] <SWPadnos> (and memory)
[19:49:59] <Nicolas35LA> ARM 64MB
[19:50:11] <Nicolas35LA> 200 MHZ
[19:50:17] <SWPadnos> hmm
[19:50:18] <Nicolas35LA> pluse train generated in hardware
[19:50:26] <cradek> ouch
[19:50:35] <Nicolas35LA> FPGA attached
[19:50:44] <SWPadnos> do you have RTAI / RTLinux compiled for that?
[19:50:44] <jepler> sounds like a neat little gizmo
[19:50:51] <Nicolas35LA> atelierrobin.net
[19:50:52] <SWPadnos> is this the Mesa 4C81?
[19:51:10] <Nicolas35LA> yes, rtai is there
[19:51:55] <SWPadnos> cool. can you point me to some code / instructions on getting that installed?
[19:52:09] <Nicolas35LA> the linux bpard is a daughter card to our ARCNC100
[19:52:25] <SWPadnos> I'm going to be getting a Mesa 4C81 (which is pretty similar, it seems), and would like to run emc on it
[19:52:29] <jepler> I'd love to see patches to support ARM incporporated in our CVS tree
[19:52:39] <SWPadnos> http://www.messanet.com if you haven't heard of them
[19:52:51] <SWPadnos> oops: http://www.mesanet.com/
[19:53:38] <erDiZz> SWPadnos, what's the price for 4C81?
[19:53:44] <SWPadnos> $300 or so
[19:54:15] <SWPadnos> $260 + $55 for a 400k gate FPGA, in single qty, with 64M RAM and 64M flash
[19:54:21] <erDiZz> looks fine
[19:54:53] <SWPadnos> yeah - I should call them to see if they're in stock again
[20:12:28] <robin_sz> meep?
[20:12:42] <eholmgren> meep
[20:12:50] <robin_sz> well, thats my experiments for the evening done
[20:13:29] <robin_sz> today I was experimenting with cats and parcel tape, to try and reproduce that video we noted on YouTube
[20:14:00] <eholmgren> do they still have claws?
[20:14:15] <robin_sz> all cats have claws
[20:15:37] <robin_sz> anyway, the results are:
[20:16:05] <robin_sz> not all cats seem to be persauded to crawl along the floor, just because they have parcel tape on their back
[20:19:15] <giac_awy> giac_awy is now known as giacus
[20:19:37] <giacus> hello robin
[20:20:51] <skunkworks> that just sounds wrong.
[20:20:51] <skunkworks> :)
[20:21:10] <skunkworks> laser pointers are the best cat toy.
[20:21:39] <SWPadnos> it's only fun until someone loses an eye
[20:25:00] <skunkworks> our cats think ceiling fans are birds of prey
[20:29:05] <owad> What does the bleeder resistor do in an unregulated linear power supply?
[20:29:36] <SWPadnos> it bleeds off capacitor charge, so you don't get shocked a few days later
[20:29:39] <jepler> owad: ensures that after mains power is removed, any smoothing capacitor drains down to near 0V in a short time
[20:29:40] <jepler> or, what SWPadnos said
[20:30:22] <owad> How do you determine how much resistance you need?
[20:31:15] <SWPadnos> you decide on how long you want it to take to discharge (maybe 5 to 30 seconds or so), look at the voltage, and use the RC time constant formulas to pick a resistance
[20:31:27] <jepler> and how you define "discharge" -- under 1V?
[20:31:38] <SWPadnos> also, you have to take into account the current the caps are meant to supply
[20:32:56] <SWPadnos> for example, deciding that discharged means "<12V within 30 seconds" , and starting with a 48V supply with 12000 uF caps
[20:33:03] <owad> I ordered the parts I needed to build the power supply a few months ago, but now I can't find the bookmark I used to figure out what I needed, which is a bit of a mess.
[20:33:17] <lerneaen_hydra> 'lo
[20:33:43] <SWPadnos> owad, what is your supply voltage, and what caps do you have?
[20:33:49] <SWPadnos> hi LH
[20:34:49] <owad> the power supply is 24V
[20:34:57] <owad> (one for each stepper)
[20:35:21] <owad> the caps are 50000uF (two for each stepper)
[20:35:27] <SWPadnos> O_O
[20:35:32] <owad> and then I have a rectifier bridge
[20:35:57] <owad> The drive is a Microstep from EAS
[20:36:02] <SWPadnos> is that 50000 uF total per supply, or two x 50000 prer supply
[20:36:08] <SWPadnos> s/prer/per/
[20:36:18] <owad> two x 50000 per supply
[20:36:30] <SWPadnos> that sounds like way more than you need. what current are the motors?
[20:36:59] <eholmgren> robin_sz: my cat runs sideways when he has tape stuck to him
[20:37:16] <owad> they're the 240 oz/in from homeshopcnc
[20:37:17] <owad> one sec
[20:37:28] <owad> 3.2v
[20:37:41] <SWPadnos> ~2.8A?
[20:37:46] <owad> yes
[20:37:58] <SWPadnos> ok. I only see a 260 - wasn't sure it's the same
[20:38:18] <owad> oh wait, that's what I'm looking at too
[20:38:30] <owad> checkign what I really have…
[20:38:32] <SWPadnos> it's probably very close to that
[20:38:55] <owad> yeah - it's the 260 oz/in
[20:39:21] <owad> when I ordered the parts, I was following a schematic and formula in a pdf for another similar stepper drive
[20:40:06] <SWPadnos> hmmm. the formula Mariss gives (which is pretty reasonable) is that you need 80000*I / V uF caps on your supply
[20:40:22] <SWPadnos> (technically, that should be 83333 *I, but who's counting)
[20:40:34] <SWPadnos> that gives me 8666 uF for you, not 100000
[20:41:09] <SWPadnos> you runthe risk of burning up your transformer with that much capacitance, unless I'm missing something
[20:42:03] <owad> hmm… I recall the pdf I was looking at gave a recommended range, and I went on the high end, thinking high capacitance would just guarantee all the more that the voltage doesn't drop
[20:42:29] <SWPadnos> it's counterintuitive, but too hig a capacitance can destroy the transformer
[20:42:33] <owad> but it wasn't _that_ big of a difference
[20:42:34] <SWPadnos> high
[20:42:37] <eholmgren> too much inrush?
[20:42:55] <SWPadnos> not inrush, but continuous operating
[20:43:33] <SWPadnos> every cycle, the transformer only provides current once the voltage goes above the cap voltage. all the power being used has to be transferred in that small percentage of the cycle
[20:44:15] <SWPadnos> if you decrease the conduction phase (by increasing capacitor "stiffness"), you have to increase the transformer current
[20:44:54] <SWPadnos> since heating is I^2 * R, you get a square-law increase in heat, and a linear reduction in time, so you have a net linear increase in transformer heating
[20:45:37] <owad> I know I've got some smaller capacitors down in the garage. How much leeway do I have in capacitance?
[20:46:13] <SWPadnos> probably 0.5x to 2x or so. I may have screwed up some decimal point somewhere, but you may want to look at it again
[20:46:20] <SWPadnos> it changes the output ripple
[20:47:14] <owad> 'off to find one. Thanks!
[20:47:22] <SWPadnos> sure
[20:47:32] <SWPadnos> hopefully it's actually a help, not just extra work for you :)
[21:20:29] <owad_> I found:
[21:20:41] <owad_> one cap that's rated 8,600 uF
[21:20:49] <owad_> one that's 4,200
[21:20:59] <owad_> and for that are 6,300 uF
[21:21:01] <owad_> four
[21:21:14] <owad_> so the 8,600 is a no-brainer
[21:21:32] <owad_> do you think I'm better off with 6,300 or 10,500 for the other?
[21:43:09] <SWPadnos> owad_, depends on the current you need. the 8666 uF calc was from a current of 5.6A (2x2.8) - you probably don't need that much, so the 6300 should be fine
[21:44:57] <owad_> were you calculating for both motors?
[21:45:09] <SWPadnos> I thought each supply had one motor
[21:45:17] <owad_> yes
[21:45:57] <SWPadnos> ok. the current is 2.8A, and depending on the driver, you may have full current in one phase and some in the other (half or 1/sqrt(2))
[21:46:40] <SWPadnos> using Mariss' formula, 80000 *I / V, I get 80000 * 2.8 / 24 = 9333
[21:46:52] <SWPadnos> hmmm - I wonder what I did last time to get 8666 :)
[21:47:09] <owad_> heh :-)
[21:47:46] <SWPadnos> ah - I mistyped 2.8 as 2.6
[21:50:00] <owad_> my transformers are rated at 24v, 10A. Do you think I need both?
[21:50:22] <SWPadnos> I'd say probably not
[21:50:51] <owad_> Any harm in using one power supply for both motors (I can't remember why I wanted to do them separately)?
[21:51:13] <SWPadnos> if you do go to one supply, then you probably want all 3 capacitors on it
[21:51:24] <awallin> anyone know what happens if you drive a standard induction motor designed for 50Hz/3000rpm at higher frequencies? I would want up to about 6000rpm or 100Hz
[21:51:23] <SWPadnos> I don't think so. that's what most people do
[21:51:30] <owad_> You mean 3 6800 uF's?
[21:51:38] <SWPadnos> awallin, you probably destroy the bearings
[21:52:00] <awallin> SWPadnos: but electrically, are there any problems?
[21:52:04] <owad_> 6300 uF, actually
[21:52:09] <SWPadnos> owad_, oh - you had written "for" - you meant "four"
[21:52:17] <owad_> yes
[21:52:42] <rayh> Most newer motors will allow 2x frequency. Some even publish ratings at over frequencies.
[21:52:51] <SWPadnos> owad_, a total of between 17000 and 20000 uF should be good, so three of those would probably do it
[21:53:13] <owad_> any tips on testing caps? I don't know where these came from
[21:53:18] <SWPadnos> awallin, the only trouble might be that you need higher voltage to get the same torque, which is higher total power
[21:53:27] <awallin> I'm using a cheap V/f VFD right now, but the torque drops off really quick after 50Hz. I'm thinking with a vector VFD I could get the higher rpm and good torque ?
[21:53:47] <SWPadnos> owad_, nope - electrolytics sometimes die and I'm not sure how to look for that without a scope
[21:54:13] <owad_> I think these are new old stock
[21:54:15] <SWPadnos> awallin, right - you get constant torque (current) below the rated frequency, and constant power above
[21:54:35] <SWPadnos> in the constant power region, you need to decrease torque as you increase speed
[21:55:14] <awallin> ok, but above the rated speed, would a vector VFD help, or am I power limited anyway and torque will drop off
[21:55:34] <SWPadnos> you're power limited anyway, and torque needs to drop off
[21:55:52] <SWPadnos> that will vary somewhat from motor to motor, but the general rule is to not exceed the power rating
[21:56:24] <lerneaen_hydra> awallin; your blog is broken for me on your noux pics entry
[21:56:30] <lerneaen_hydra> the image is over the text
[21:56:33] <awallin> ok. It's just that all the standard industrail motors are rated at 3000rpm, and that's a little too slow for small endmills... so I'd like to find something that goes to 6000rpm.
[21:56:35] <lerneaen_hydra> FF 2.something
[21:56:57] <awallin> lerneaen_hydra: can you paste the url
[21:57:00] <lerneaen_hydra> http://www.anderswallin.net/ ?
[21:57:10] <owad_> I've got to run. Thanks for the help today.
[21:57:12] <SWPadnos> awallin, yes - as Ray said, some motors are rated to go faster than their synchronous speed
[21:57:19] <lerneaen_hydra> http://www.anderswallin.net/2007/01/noux-pics/ there too
[21:57:24] <SWPadnos> if you want to buy a motor, look for "inverter duty"
[21:57:27] <lerneaen_hydra> FF and konq
[21:57:28] <awallin> firefox works for me
[21:57:56] <awallin> lerneaen_hydra: ah, yes it's "broken" over here also
[21:58:26] <awallin> lerneaen_hydra: it's even more broken with ie...
[21:58:35] <lerneaen_hydra> awallin; http://lerneaenhydra.shacknet.nu/images/files_temp/snapshot4.png
[21:59:24] <anonimasu> hm
[21:59:33] <awallin> lerneaen_hydra: yep, that's what I get too. Looks like browsers don't like the way wordpress positions pictures. better to just have them plainly in the text, and not aligned left or right...
[22:00:09] <awallin> SWPadnos: I'm wondering if a big DC servo might be a more straigtforward solution for a ca 1-2kW spindle that would go up to 6000rpm
[22:00:52] <SWPadnos> a big fast servo of some kind may be the answer, if you need to control the speed electronically
[22:01:12] <SWPadnos> this is why it's still a good thing to have a pulley set - you get full power in all the speed ranges
[22:01:43] <lerneaen_hydra> bah, g'night all
[22:01:47] <awallin> SWPadnos: yes, rigid tapping would be on the wish list sometime in the future.
[22:01:58] <awallin> lerneaen_hydra: I fixed that particular page, but there are probably more
[22:02:51] <awallin> pulleys wouldn't really fit on our small spindle-head...
[22:03:17] <SWPadnos> it's kind of hard to get everything you want out of one motor
[22:03:38] <SWPadnos> a DC (or AC) servo has a particular power rating at some speed
[22:04:15] <SWPadnos> below that speed, the power decreases linearly - it's actually a torque rating
[22:04:49] <awallin> yep, on the minimill we want to do from 40mm face-mill down to 6mm ball end for 3D finishing, quite a large range of speed/torque requirements
[22:04:50] <SWPadnos> so if you want a spindle that runs from 60 - 6000 RPM, you're basically going to have 1/100 the power at the lower speed (since the torque is constant)
[22:05:25] <SWPadnos> there's no way around that unless you use a mechanical speed changer
[22:05:52] <SWPadnos> (of course, servos can give peak power that's much higher than continuous, so it can work out in the end ...)
[22:06:01] <awallin> how much does changing from Y to delta winding on an ac motor help?
[22:06:11] <awallin> in the low rpm range
[22:06:15] <SWPadnos> I have no idea - you'd have to ask someone like Ray or jmk
[22:06:19] <awallin> I understand this is how the pros do it
[22:06:31] <SWPadnos> (I only know the theory on those - not application ;) )
[22:09:29] <anonimasu> hm
[22:09:40] <anonimasu> how do you differ from a nullmodem cable and a normal serial cable?
[22:10:14] <awallin> some wires are crossed in one type and go straight in the other. google is your friend :)
[22:10:25] <anonimasu> I were wondering if anyone knew
[22:10:29] <anonimasu> ;)
[22:10:50] <SWPadnos> on a 9-pin connector, pins 2 and 3 are crossed for a null-modem and straight through for - err - straight through :)
[22:11:00] <anonimasu> heh
[22:11:02] <SWPadnos> I think it may be the same pins on a DB-25
[22:11:08] <anonimasu> I have a db9F to db25m
[22:11:10] <SWPadnos> (but opposite meanings)
[22:11:15] <anonimasu> but I dunno if it's a nullmodem
[22:11:18] <SWPadnos> oh, then you'll have to look it up ;)
[22:11:28] <anonimasu> yeah
[22:11:52] <SWPadnos> that's meant to connect a computer to a DB25 modem, I'll bet, and won't be null-modem
[22:41:52] <josesito> hi all
[22:43:39] <josesito> i'm studying industrial engineering and i started "fabrication processes" (don't know if that's the name in english). and i might need a software which helps me simulate some machine functions
[22:44:35] <josesito> i would like to know, if emc is also able to simulate what the machine will do if i enter the codes, or if it's just a machine-communication backend for linux
[22:45:24] <anonimasu> josesito: well it will draw your toolpaths
[22:45:57] <anonimasu> will..
[22:46:32] <josesito> anonimasu, thanks for the answer. i can use it for testing purposes in my home (withouth the actual machine?)
[22:46:43] <alex_joni> josesito: yes
[22:46:52] <alex_joni> you can "dry"-run the machine
[22:47:00] <josesito> what is that?
[22:47:00] <alex_joni> and preview the movement of the virtual tool
[22:47:06] <josesito> oh
[22:47:08] <alex_joni> run without motors attached
[22:47:54] <alex_joni> josesito: the simplest thing to do is get the Live CD from linuxcnc.org, boot it (it doesn't need to install anything), then start emc from the menu and run the sim/axis configuration
[22:48:27] <josesito> what are the requisites for compiling??
[22:50:40] <anonimasu> get the livecd..
[22:50:41] <anonimasu> :)
[22:50:58] <josesito> that hard to compile?? :$ =)
[22:51:06] <anonimasu> not worth the trouble
[22:51:14] <anonimasu> it may be easier when you just want to run sim
[22:51:46] <alex_joni> josesito: the list is a bit long for compiling..
[22:51:59] <alex_joni> tcl,tk, gcc, python, etc
[22:52:00] <josesito> it's just i don't like getting out of my system just to run the program... can i at least get binary packages and run it without installing?
[22:52:12] <josesito> btw. i'm running archlinux
[22:52:16] <alex_joni> josesito: what system are you running?
[22:52:22] <alex_joni> what kind of packages does it use?
[22:52:47] <josesito> .pkg.tar.gz
[22:53:05] <josesito> it has it's own package managment system
[22:53:12] <josesito> i'm looking for it right now
[22:53:57] <alex_joni> there are binary packages for Ubuntu only
[22:54:20] <alex_joni> I guess you need to grab the sources, and use the usual ./configure, make, sudo make install
[22:55:33] <josesito> k
[22:55:33] <josesito> i'll try that
[22:55:34] <josesito> brb
[22:55:41] <alex_joni> hang on
[22:55:43] <josesito> just another thing
[22:55:53] <alex_joni> you will want ./configure --enable-simulator
[22:55:56] <josesito> where can i learn more from the language??
[22:56:00] <josesito> oh ok
[22:56:03] <josesito> thanks
[22:56:06] <alex_joni> as you don't have a realtime kernel
[22:56:16] <alex_joni> josesito: the User manual is quite good for basics
[22:56:33] <alex_joni> http://linuxcnc.org/docs/2.1/EMC2_User_Manual.pdf
[22:57:09] <josesito> thanks!
[22:57:12] <josesito> ok, brb
[23:06:26] <paragon36> Hello All... Would this controller be OK for a 180vdc motor that only has + - gnd cable?
[23:06:34] <paragon36> http://cgi.ebay.co.uk/KB-BALDOR-BC142-3HP-DC-MOTOR-DRIVE-W-HEATSINK_W0QQitemZ290016457393QQihZ019QQcategoryZ1267QQrdZ1QQcmdZViewItem
[23:06:55] <alex_joni> does this link work for anyone?
[23:06:59] <alex_joni> http://www.uclinux.org/pub/uClinux/dist/uClinux-dist-test-20070108.tar.gz
[23:07:10] <alex_joni> (by work I understand more than 5kB/sec)
[23:07:24] <paragon36> The ebay link Alex?
[23:07:41] <alex_joni> paragon36: no, the uclinux link I posted
[23:08:03] <paragon36> Ooops sorry I have a delay on this connection ... ;-)
[23:08:32] <jepler> alex_joni: I started at 9KB/s but it is decreasing .. down to 6KB/s now
[23:08:47] <alex_joni> argh.. that is such a crappy server
[23:09:31] <alex_joni> I think it limits download speed on purpose
[23:11:11] <jepler> paragon36: looks like there are specs here: http://www.baldor.com/products/detail.asp?1=1&catalog=BC142&product=DC+Controls&family=OneWay%7Cvw%5FDCControls%5FOneWay
[23:11:51] <paragon36> I was alittle confused regarding the motor connections as the diagram has for wires from the motor?
[23:12:59] <paragon36> Armature = 2 connection | field winding = 2 connections?
[23:13:30] <paragon36> Hello Skunkworks!
[23:13:38] <skunkworks> Hello
[23:13:54] <skunkworks> whats new?
[23:16:17] <jepler> paragon36: I dunno, there doesn't seem to be much information about these controls...
[23:16:31] <paragon36> Being trying to get this motor controller working that I blew the other day.... got the 12 v suppy working but am seeing 240V dc on the motor output. have replaced the op-amps, SCR's, Rectifier ... but its no go ... So was asking group about a driver ive seen on ebay.
[23:18:33] <paragon36> Yeah I'm a little confused to know if this would work on a normal 2 lead dc motor... I dont understand the armature and field winding connection.
[23:19:04] <paragon36> Should ask the seller the question I guess.....
[23:22:50] <SWPadnos> alex_joni, if you want to put it on linuxcnc or cncgear, be my guest
[23:23:30] <paragon36> Thanks Jepler for your help anyway Jepler :-)
[23:23:52] <paragon36> Err pls ignore my poor, poor grammar!
[23:25:10] <SWPadnos> paragon36, if it has armature and field connections, then it's for a different kind of motor than a "standard" DC servo
[23:25:26] <SWPadnos> I don't know if you can make it work, but it may be possible
[23:25:31] <alex_joni> SWPadnos: found a faster mirror
[23:25:47] <SWPadnos> someone like Jon Elson or John Kasunich may be able to tell you
[23:25:49] <SWPadnos> alex_joni, cool
[23:25:58] <alex_joni> but I must say I find uclinux insane
[23:26:02] <SWPadnos> heh
[23:26:09] <alex_joni> their latest package decompresses to 1.2GB
[23:26:21] <SWPadnos> that's not exactly micro, is it?
[23:26:21] <alex_joni> not my idea of a small system
[23:26:34] <paragon36> Thats a shame SWPadnos as the price is good.... BTW what sort of motor would it be called?
[23:26:49] <alex_joni> you compile all that into a krnel which is 1MB at most
[23:26:51] <SWPadnos> I can't remember - that's why I was vague about it ;)
[23:27:12] <alex_joni> omg.. it even has samba
[23:27:24] <alex_joni> mysql
[23:27:46] <SWPadnos> it looks like they've included everything that works on uclinux, and you can select the packages you want for your own device
[23:28:17] <SWPadnos> so it is pretty small compared to the many-gigabyte archives of stuff available for e.g. Ubuntu :)
[23:56:25] <col> hello
[23:56:42] <col> anyone about?
[23:56:48] <alex_joni> oh darn.. of course it doesn't work with 2.95.3 anymore
[23:57:00] <alex_joni> and the toolchain I have for arm is 2.95.3 :(
[23:57:32] <col> just about to order a motenc
[23:57:45] <col> was wondering between the motenc lite
[23:58:00] <col> the cheaper one doesnt have the ADC inputs
[23:58:14] <col> and only 4 DAC outs
[23:58:42] <col> is that likley to matter with a 3 axis mill ?
